conf: support manually specifying VFIO variant driver in <hostdev> XML This patch makes it possible to manually specify which VFIO variant driver to use for PCI hostdev device assignment, so that, e.g. you could force use of a VFIO "variant" driver, with e.g. <driver model='mlx5_vfio_pci'/> or alternately to force use of the generic vfio-pci driver with <driver model='vfio-pci'/> when libvirt would have normally (after applying a subsequent patch) found a "better match" for a device in the active kernel's modules.alias file. (The main potential use of this manual override would probably be to work around a bug in a new VFIO variant driver by temporarily not using that driver).
